中国省域新质生产力水平的测度及其时空演变
Measurement of Provincial New Quality Productivity Level and Its Spatiotemporal Evolution

本文以2013~2022年我国30个省份为研究对象，构建了中国省域新质生产力水平指标体系，并基于熵值法进行了测算，采用东中西三大区域划分视角，利用了核密度估计方法和Dagum基尼系数分解法分析了中国省域新质生产力水平的区域差异及时空演变。结果表明，东部地区新质生产力水平远高于其他地区的新质生产力水平；全国的新质生产力水平差异整体呈扩大趋势，中国新质生产力区域差异主要是地区间差异造成的；东北地区新质生产力水平显著存在两极分化特征，存在明显的空间极化现象。本文旨在为提高新质生产力的相关政策制定提供了科学依据。
This study focuses on the 30 provinces in China from 2013 to 2022, constructing a provincial-level index system of new quality productivity and calculating it based on the entropy method. Adopting the perspective of dividing the country into eastern, central, and western regions, this study utilizes kernel density estimation method and Dagum Gini coefficient decomposition method to analyze the regional differences and spatial-temporal evolution of new quality productivity in Chinese provincial areas. The results indicate that the new quality productivity level in the eastern region is significantly higher than that in other regions; the overall difference in new quality productivity level in the country is expanding, mainly caused by inter-regional differences. The northeastern region shows significant polarization in new quality productivity level, highlighting spatial polarization phenomena. These findings provide a scientific basis for policy-making.
